SN74ACT16PWR

Overview

The SN74ACT16PWR is a single inverter manufactured by Texas Instruments, belonging to the 74ACT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device utilizes TTL-compatible input levels and provides open-drain outputs capable of sourcing up to 24 mA. Packaged in a TSSOP-14 surface-mount format, it supports an operating temperature range from -40°C to +125°C with a maximum quiescent current of 2 µA.

Feature Summary

• Schmitt-trigger input configuration enhances signal integrity by filtering noise
• TTL-compatible input thresholds ensure interoperability with standard logic families
• Open-drain output structure allows flexible interfacing and wired-logic applications

Applications

• Signal conditioning for noisy digital environments
• Interface between TTL and CMOS logic systems
• Waveform shaping and pulse generation circuits

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required industrial temperature grade and RoHS compliance status. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when Schmitt-trigger action is required for clean switching in high-noise environments. The open-drain output necessitates an external pull-up resistor for proper high-state operation. Verify that the system voltage remains strictly within the 4.5 V to 5.5 V range to prevent device damage or undefined logic states during operation.

Part Context

This device is part of the broader 74ACT series, which offers performance comparable to LS-TTL but with lower power consumption typical of CMOS technology. The ACT series is designed for high-speed applications requiring robust noise margins. The PWR suffix specifically denotes the TSSOP-14 package variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements include other SN74ACT16 variants with identical pinouts and electrical specifications. Verify that substitute components maintain the same open-drain output configuration and Schmitt-trigger input requirements to ensure circuit functionality remains unchanged.
